[pacman-dev] [PATCH] Clarify testing within conditional statements
Allan McRae

Sat Jun 19 04:58:41 EDT 2010
Follow the HACKING guidelines and always use != 0 or == 0 rather
than negation within conditional statements to improve clarity.
Most of these are !strcmp usages which is the example of what not
to do in the HACKING document.
